(AP Photo/J Pat Carter) (Newser) – The Florida man who admitted killing his wife, then posting a photo of her body on Facebook was also a self-published writer—one who urged communication to resolve marital disputes. In one of his volumes, How I Saved Someone’s Life and Marriage and Family Problems Thru Communication, Derek Medina discusses a situation similar to his own, the Miami Herald reports: A married couple gets divorced and eventually remarried. The book advises readers to talk out their problems. "Prevent accidents from happening from communication with each other," Medina writes.

She said she was "leaving him," and he followed her to the kitchen, gun in hand. She took out a knife, which he said he took from her and put away before he started shooting her. He had previously beaten her, her former boss tells the Herald.
